Subject: [PATCH] gpio: pca953x: add oftree support
Date: Wed, 29 Aug 2018 09:08:27 +0000 [thread overview]

Hi,
this Patch adds oftree support to the pca953x driver. I ported the
of_device_id table from the kernel and reduced it to the currently supported
devices in barebox (sufficient for us).
Documentation is already there [1].
